APPARA US FOR sE AR-A'Tmo OIL-VAPORS,

SPECIFICATION forming part of Letters Patent No. 313,979, dated March 1'], 18 85.

* i Application filed May 29,1854. (X0 model.)

Be itrknown, that I; Jens EDWARD BICK- NELL, of Cleveland, in the county of Cnyahoga and State of Ohio, have invented a new and Improved Apparatus for Separating Oil- Vapors, of which the following is a full, clear, and exact description. v i

My improvements relate to apparatus forthe separation of the difierent grades of -oil contained in one common stock or kind while in a vaporous state, and the invention consists in a special construct-ion having the object to insure the certain condensation of the vapors of the heavy oil, while the vapors of lighter specific gravity pass 011' separately,and also in means for accurately regulating the temperature of the condenser at all times, as hereinafter described and claimed;

. Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional elevation of the apparatus, and Fig. 2 is a vertical section of the condenser in a plane at right angles to Fig. 1.

The condensing-vessel A is an iron tank of flattened tubular form and of suitable length, having a separate chamber, a, at the top and chamber b at the bottom, formed by horizontal plates or partitions b. c c are pipes of sinuous form, or made with quick bends, extending from the top chamber, a, to thelower chamber, b, and through the plates 11'. d is a trapped pipe from chamber b. h is a pipe from chamber a to a tank, B. iis a safetyvalve. k k are water -inlet pipes entering near the upper part of the condenser, and having perforated ends for spraying the water. 1 is a steam'pipe entering the vessel A, having separate branches 1 Z, for supplying either superheated or wet steam. m is a pipe for drawing off water of condensation, and q is the pipe for supplying the oil-vapors t-o chamber b. The tank B, which is for the second separation, has a trapped outletpipe, n,

from the bottom, a pipe, 0, from the top, which will pass to a water-box, and a steamsupplypipe, 1), that connects with a perforated coil on the bottom of the tank. The vapois from the still cuter chamberlb by the pipe g, from whence they rise naturally into pipes a. By the sinuous form and sharp bends of perature than thatof thepipes, are quickly condensed and return to'chamber b, whence they pass out by pipe (I. Kihe lighter vapors, or those whose vaporizingpoint islower than 'the temperature of pipes 0, pass upward and out by pipe h to tank B, which they reaci in a condensed condition, and are heated by wet steam, sup-plied by pipe 1;,i to oil, which-covers the perforated coil on ghe bottom of the tank. The agitating and heating of the oil by the steam vaporizes and drives oil the lighterproducts by pipe 0 into a water-box, while the heavier portions, which are of too high a vaporizing-point to be vaporized by steam, but too low to have been condensed in pipes 0, go by pipe n to a cooler.

in first starting the apparatus the condenser A is supplied with superheated steam, in order to obtain a temperature igh enough to cause the first separation; 0t erwise the vapors of light specific gravity will condense and go out by pipe d-with the heavy oil. As the vapors increase in temperature and quantity the pipes c are heated more highly, and it is necessary to use wet instead of dry steam to check the rising temperature, so that the heavy vapors may condense, and later it is necessary to use hot and then cold waterin order to keep down and properly regulate the temperature of pipes c. This is allowed for by the arrangement of steam-pipes l I? and water-pipes k k.

The advantages of this apparatus over others of the same class lie in the perfect separation insured by the accurate regulation ofthe temperature and the contact of the vapor particles with the condensing-pipes caused by their sinuous form.
